TOOL.

Patented Mar. 16, 1920.

Application led March 14, 1919. Serial No. 282,631.

To all whom t may conce-rn:

Be it known that I, OTTO KAMPFE, a citizen of the United States, residing at Bellmore, in the county of Nassau and State of New York, have invented an Improvement in Tools, of which the following is a specification.

This invention relates to an improved tool, and is designed for use both as a can opener and as a tool for removing bottle caps. The general construction of tools for opening cans as now commonly Yemployed consists of a blade and a guard placed adj acent thereto t0 act as a lever for cutting the cover of a can by drawing the knife blade through the same after the knife blade has been used as a punch to make the hole in the can. In these can openers therefore, the point of the knife blade as commonly constructed extends appreciably beyond the end of the guard so as to permit the use of the point of the knife blade in punctur ing the can. Obviously, in the use of an implement so constructed, the full length of the blade cannot be utilized in making a cut in the can, and furthermore the point of the blade is normally unprotected. The object of my invention therefore is to overcome these diflieulties by providing an instrument adapted for use primarily as a can opener and in which, together with a handle, there is provided a knife blade and a movable guard adapted normally to eX tend beyond the point of the knife blade and to be movable so that the point of the knife blade may be employed to puncture the can, when as will be understood the lever may be returned to its normal position and by extending beyond the point of the blade makes it possible to employ the full length of the blade in making each cut in the can. Furthermore as hereinafter indicated, the tool is provided with a hooked extension also adapted to coperate with the guard or lever so as to be utilized as an instrument for removing bottle caps.

In the drawing:

member 23 is which the same is operated vand which han- I dle normally lies against the edge faces of` Referring to the drawing and particularly to Figs. 1 to out my invention, I prefer toemploy a handle which may be made in parts as indicated at 10, and between which a plate 11 is suitably Xed. The plate 11 extends beyond the end of the handle members and terminates in a knife blade positions on this plate 11 I also provide a lateral extension 13 which terminates in a hooked end 14.

Associated with the parts hereinbefore described, I also employ a guard which is 3 inclusive, in carrying,

1:2. In suitable preferably'composed of two members 15 and 16 of similar configuration and pivotally connected in the plate 11 as indicated at` 17. The parts of the guard furthermore are connected at one endV by a rivet or pin 18 on which is also mounted between the members of the guard a roller 19, while at the opposite ends the members 15, 16 of the guard are also riveted together as indicated at 20 with an intervening spacer member 21. As is plainly indicated in the drawing, the members 15, 16 of this' guard lie on opposite sides of the plate 11. Y i

Adjacent the inner or handle end of the members 15, 16 of the guard the same are recessed as indicated at 22 in order to receive a cam member 23 which lies within the said recesses and is pivotally connected to the plate 11 as indicated at 211. The cam fitted with a handle 25 by the handle members 10. Adjacent the outer ends of the handle members 10, the plate 11 is provided with a recess 21 in the edge thereof to receive the spacer' 21 when the guard member is at its normal position as shown in Fig. 1.

In the use of the hereinbefore described tool. the handle 25 is swung outwardly in the direction of the arrow to cause the handle to assume the position shown in dotted lines in Fig. 1, when as will be understood, the guard member may be turned on its pivotal point to also assume the position shown in dotted lines in Fig. 1. When in this position, the point of the blade may be used to puncture the top of the can to be opened. After this is done, the guard member is turned so that the cam 23 will enter the recess 29. and may be turned bv the handle-` tended beyond the point of the blade position shown in Fig. l, so as to lock the guard in place, when, as Will be understood, the point Aof the blade'may be inserted again in the hole made in the `can and the tool used as an ordinary can opener. the forward end of the uard member acts as a lever against which die cut is made, and inasmuch as this lever extends appreciably beyond the point of the blade, the entire length of the blade may be utilized in making eachcut inthecan. Furthermore as Will be readily understood, the opposite side of the forwardv end ofthe guard member acting in conjunction with the hooked end. 14 of the extension lanay be employed as tool for removing bottle caps.

By referring to Figsando, it will be seen that instead of mounting the Vguard member so as to swing on the blade forniing part of the tool, this guard member may be merely slidable thereon from one position to another so as to norn'ially lie eX- to extend therefrom sufficiently far to permit the point of the blade to be used to puncture a can tobe opened. In these figures of the drawing, the parts of the guard member are indicated at 2.6 and 27. At the forward end they are connected by a rivet in the same manneras the guard member hereinbefore described. In veach of these parts Iof the guard member, there are similarly placed slots 28 adapted to receivepins 29 fixed in the opposite faces of the plate ll so that as Will be understood, theV guard Amember In so doing, i

connected thereto as indicated at may be moved along the plate from thc position shown in full lines to that indicated in dotted lines in' Fig. 4. In this cons-truction of the invention, the extension 13 is provided with a paWl 80 which is pivotally 3l and the tooth of the pawl is adapted to enter a notch 32 in the edges of the parts 26 and 27 of the guard member to maintain the same in its operative position as shown in Fig. 4, this being done as will be understood by the user placing his thumb against the surface of the pawl to maintain the same in place.

`I claim as my invention: v

lp. A tool of the class'v described, a knife blade, a. guard member pivotally connected to the knife blade, and a cam member also pivotally connected to the knife blade and adapted toV move in a recess provided therefor in the guard to lock the same in its normal operative position.

2. In atool of the class described, a knife blade, a tivo-part guard member spanning the said knife blade and pivotally connected thereto Withthe forward end of the guard member normally extending an appreciable distance beyond the point of the knife blade, and a cam member also pivotally connected to the saidvbladefand adapted to move in recesses provided therefor the said guard to lock the same in a normal operative position.
